METHOD OF MAKING SEAMS.

SPECIFICATION forming part of Letters Patent N 0. 501,478, dated July 11, 1893.

Application filed October 29, 1888. Serial No. 289.461. (No specimens.)

T aZZ whom/ it may concern.-

Be it known that I, SAMUEL JAROS, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements Relating to Methods of Making Seams, of which the following is a full, clear, and exact description, whereby any and elastic, and one that will not rip out.

The object of my improvement is to make up garments with such a seam, and my invention consists in the peculiar method of making a flat, firm and elastic seam by joining the edges of two pieces of fabric by through and through stitching with thread, then trimming the united edges, flattening the parts, and then overstitching the seam, as more particularly hereinafter described and pointed out in the claims.

Referring to the drawings: Figure 1 is an outline view of an undershirt, that is an article to which my improvement is particularly adapted. Fig. 2, is a view showing two pieces of fabric, the one superposed upon the other with the line of through and through stitches set within the edge and trimmed. Fig. 3, is a View of the same opened out flat and having a line of zigzag stitches overcasting the through and through stitches. Fig. 4, is a View showing the reverse of the fabric in Fig. 3.

In the accompanying drawings my improvement is illustrated in connection with an article of underwear in the making of which it is particularly adapted, although'l do not limit myself to its use in this particular undershirt a. The shirt is made of a peculiar fabric that is of knitted goods, and is fleece-lined, the knitted fabric 1) having united with it a lining or fleece c, of any desired fiber as wool, usually incorporated with the cloth in knitting the latter. The edges of the pieces of cloth (I and e, of whatever fabric and texture they may be, are, in the practice of my improvement, laid one upon the other and are united near one edge by running a seam f, that may be done by hand, but preferably by the use of any of the ordinary sewing-machines. After sewing the pieces together in the above described manner, or while they are being sewed, the edges are trimmed quite close to the seam f, leaving them as shown in Fig. 2 of the drawings. While sewing the first seam the tension on the thread is preferably quite loose. After forming the first seam and trimming the edges the pieces are opened out fiat and the seam is pressed down while it is being sewed over and over with the overstitch g, as shown in Figs. 3 and 4 of the drawings. The result is a: seam that is extremely strong and is peculiarly elastic, and is one that will not readily rip even when subjected to the hardest usage. This seam is adapted to various kinds of fabrics, but is particularly useful in making garments and the like from fleece-lined knitted cloth.

I claim as my invention- 1. The herein described method for the formation of a seam which consists in placing two pieces of fabric one upon the other, sewing a straight line of stitches adjacent to one edge of the pieces of fabric, then spreading out the two pieces of fabric so that theylie in the same plane, and finally further securing the seam of the united pieces of fabric by sewing a zig zag line of stitches over the seam of straight stitches passing the stitches over the seam successively from one piece of fabric to the other when the two united pieces are spread out.

2. The herein described method for the pro-' duction of a seam in garments consisting of placing two pieces of fabric to be united one upon the other, then uniting said pieces of fabric together by a straight line of stitches and simultaneously therewith trimming the surplus material close to the line of stitches, then spreading the two pieces of fabric so as to bring them into the same plane, and finally strengthening the seam so formed by sewing a zig zag line of stitches over the seam of straight stitches passing the stitches over the seam successively from one piece of fabric to the other when the two united pieces are spread out.

3. The herein described method for the production of a seam in garments consisting of placing two pieces of fabric to be united one upon the other, then uniting the said pieces of fabric together by sewing a straight line of stitches and simultaneously therewith trimming the surplus material close to the line of stitches, then spreading the two pieces of fabric so as to bring them into plane and fin 11y strengthening the seam so formed by sewing a zig zag line of stitches over the seam of straight stitches, portions of the zigzag 15 stitches passing through the fabric outside of the straight line of stitches so as to entirely inclose them, passing the stitches over the seam successively from one piece of fabric to V the other when the two united pieces are 20 spread out.
